The complexation equilibria of vanadium(V) with 8-quinolinolate ion(ox) were investigated spectrophotometrically. Depending upon the acidity of the solution various 1:1 and 1:2 complexes are formed: VOox, VOHox, VOox, and VOox. the formation and protonation constants of ...
Solubility: ≥ 2.5 mg/mL (13.92 mM); Clear solution 此方案可获得 ≥ 2.5 mg/mL (13.92 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。 以1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。 *以上所有助溶剂都可在 上海金畔...
From the solution processing of hydrophilic molecules to polymer-phthalocyanine hybrid materials for ammonia sensing in high humidity atmospheres. We have prepared different hybrid polymer-phthalocyanine materials by solution processing, starting from two sulfonated phthalocyanines, s-CoPc and CuTsPc,... P...
The rate of palladium extraction from chloride solutions by 7-(1-vinyl)-3,3,5,5-tetramethylhexyl)-8-quinolinol (KELEX 100) increased more than six hundred times when as little as 2 脳 10M thiocyanate was added to the aqueous solution. Si... M Kawashima,H Freiser - 《Analytical Chemistr...
Studies have been made on the coordination behaviour of the aluminium(III) 8-quinolinol-5-sulfonate (hqs)1 and aluminium(III) nqs1 complexes2 with hqs in 0.1 mol dm2 aqueous sodium chloride solution at 25掳. Mixed-ligand complex formation was evidenced by electronic absorption spectral and ...
•5-ClM-8-HQ is good mixed-type inhibitor for steel in HCl solution.•Maximal inhibition efficiency is 97% at 298K with 1.0mM of 5-ClM-8-HQ.•EIS measurements indicate the formation of a protective film at the metallic surface....
